Amazon opens its trucking service to all businesses, pressuring major freight carriers' stocks.

Amazon announced it will expand its less-than-truckload (LTL) shipping service to all businesses across the U.S., not just those shipping to its own warehouses. This move allows companies of all sizes to use Amazon's logistics network for nationwide freight delivery. The announcement caused shares of major freight carriers like Old Dominion, ArcBest, Saia, XPO Logistics, and FedEx Freight to drop, reflecting investor concerns about increased competition. Amazon's growing logistics capabilities, including planes, vans, and thousands of trailers, are increasingly challenging traditional carriers as it offers more services to external customers.
